Boston, Seattle, San Diego, San Francisco and Silicon Valley are cornering the market on innovation jobs in the U.S., according a new report published in the New York Times.

The report is by Mark Muro and Jacob Whiton from the Brookings Institution’s Metropolitan Policy Program, and Rob Atkinson of the Information Technology and Innovation Foundation, a research group that gets funding from tech and telecom companies. They identified 13 “innovation industries” — which include aerospace, communications equipment production and chemical manufacturing — where at least 45 percent of the work force has degrees in science, tech, engineering or math, and where investments in research and development amount to at least $20,000 per worker.

Those five cities captured nine out of 10 jobs created in these industries from 2005 to 2017, according to the report.

The article raises the question of whether the country will be increasingly divided between the haves and the have-nots.

The authors argue that a broad federal push is needed to spread the business of invention beyond the 20 cities that dominate it. “Hoping for economic convergence to reassert itself would not be a good strategy,” Mr. Muro said.

And there are additional strategies that other regions can take, according to a recent report from the Information Technology and Innovation Foundation.
